Popular workplace app Slack is preparing to go public, and it warns investors it may become a target of nation state hacking.

Companies that are preparing to go public—such as Uber, Lyft, Pinterest, Snapchat, and PagerDuty—all have sections in their S-1 registrations that address the threat of “unauthorized access” to their software, systems, and technologies. However, none of these companies explicitly referred to “organized crime” or “nation-states,” as Slack did in its S-1 filing.

Ms. Haskins also reminds us that Slack doesn’t have end-to-end encryption, and in some cases your boss can download and read your entire Slack history without you knowing.

Slack offers a Remind feature that can help keep things from slipping through the cracks. You might not have noticed it, however, so Bryan Chaffin wants to show you how to use it to remind yourself, your colleagues, or even delay action on a message.
